Transformer Lamp System, late 1950's

Historical information

This transformer lamp system, which has a dial to transform 240 volts to a minimum of 32 volts was used by electrical technicians to inspect internal parts of the large generators (even in small confined spaces). The reason for the reduction of the 240 volts to the 32 volts was for the safety of the inspector. The SEC Victoria Hydro Scheme's electrical generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro schemes was achieved from the mid 1900's to the 1960's. At this the point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce inclusion of skilled and unskilled migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.

Significance

This transformer lamp is very significant to the Kiewa Valley as it was introduced as a very small part of the explosion of human resources into the valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both industrial and larger residential community. This evolution in the valley created a change, not only in the "physical" landscape but also the socio-economic expansion which permitted other "tourist" based industries into the valley. This is also a specific electronic item which was manufactured in Melbourne and not sourced from Europe or Asia. This demonstrates the fast evolution of Australian technology to a high standard compatible to that of the rest of the world.

Physical description

This heavy hand held electrical transformer (transforms 240 volts to 32 Volts) an has one leather handle on the top with three small (gauze filtered) air holes. It also has two 2 pin directional cable distribution (clipsal) in/out points 10amps / 240 volts. There is one glassed in volts/ac meter and one variable switch (180 to 150 voltage in settings of 10 volt increments.There are two vents (one on each of the smaller sides). There is also one three pin electrical lead coming out from the top.

Inscriptions & markings

On one side is a manufacturer's plaque with "ELECTRONIC A & R EQUIPMENT MELBOURNE" and underneath "TYPE 1719, PRI V. 180 250" underneath "V.A. 1250" underneath "CYC 50" underneath "SEC V. 115" underneath "SEC A. 10 . 8". The label on topside "CAUTION SET SWITCH TO 250 v BEFORE CONNECTING TO MAINS THEN, WITH EQUIPMENT OPERATING, SET METER TO RED LINE.
